The Ministry of Health warns the population of the risks posed by excessive exposure to sun and, to avoid them, recommends following safety rules. The doctors’ alert comes after the State Hydro-Meteorological Agency forecasted for 16-22 July high temperatures of up to 41ºC. The most exposed to heat stroke risks are children, the elderly and people suffering from cardiovascular diseases. On hot days doctors recommend a minimum intake of 3 litres of water, use of umbrellas, and light clothing, preferably with long sleeves. The main sunstroke signs are acute headaches, abundant perspiration, nausea, high body temperature, weak and rapid pulse. Until emergency care arrives, heat stoke victims must be moved into a cool place and laid with the head higher than the body. To give first aid, remove the clothing and either wrap the person in a cold, wet sheet; sponge the person with towels or sheets that are soaked in cold water; or spray the person with cool water. Put ice packs or cold compresses to the neck, under the armpits and to the groin area. Do rescue breathing if the person is not breathing, and cardiopulmonary resuscitation if the person has no pulse, until emergency care arrives. According to statistics, there were registered 11 cases of sun and heat stroke this year.
